CAR CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 5, 1907.

To all whom it may concern.-

Be it known that I, ETHAN I. DoDDs, a citizen of the United States, anda resident of Avalon, county of Allegheny, State of Pennsylvania, haveinvented certain new and useful Improvements in Car Construction, ofwhich the following is a specification.

In the system of car construction which I have devised and which isshown and de scribed in a number of applications for United StatesLetters Patent a recurrent feature is that of making the parts easy ofrepair and replacement in case of injury or distortion from any cause.This inventive idea is ap plied in certain of my inventions to the carsides and the car ends, as fully set forth in my applications filed onthe 18th day of June, 1904, and bearing the SerialNos. 213,139 and213,140.

The present invention relates to a novel construction of the car-sills,particularly the side and center sills, whereby an injured sill can bemore readily repaired or replaced than is at present the case. This ispartly due to the fact that the sill herein disclosed is made up ofseveral parts, not less than three in number, so that the entire silldoes not in many cases need to be treated in a furnace for the purposeof straightening it or otherwise restoring it to its original condition,while a wholly-disabled member of the sill can be replaced withoutrequiring an excess ive amount of unriveting and riveting. Moreover,irrespective of the advantages named the sill which I disclose herein isoriginally easy of construction, while at the same time it serves whenin position as an e'liicient member of the car construction, well suitedto its normal purposes.

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of a portion of a car-body having myinvention applied thereto. Fig. 2 is a partial transverse section takenon line 2 2 in Fig. 1 and Fig. 3 is a transverse section of apassenger-car, illustrating a modification.

Referring more particularly to the drawings, 1 and 2 are angular tensionmembers of a side sill for a railway-car, the same being formed in threeparts, two of which are shown in Fig. 1. The parts 1 and 2 are joined byan angular butt-strap 3, placed underneath their adjacent ends, whilethe butt-strap itself or the ends of the members 1 and 2 are joined byrivets (shown at 4) to one of the T- shaped side stakes 20 20, utilizedin the construction of the car side. The part 2 is the central elementof the tension member of the side sill, while the part 1 is extended asa continuation of the side sill toward the end of the car. In being thusextended the part 1 passes by the body-bolster and is connected at itsend to a subsill 5 of channel cross-sec tion.

The parts 1, 2, and 3 may be regarded as forming the tension member ofthe side sill, while the compression member thereof is constituted by anangular piece of metal 6, running lengthwise of the car, secured to theseveral side stakes thereof and, like the tension member 1, passingbeyond the body-bolster and secured to the subsill 5. It will be seenthat the members 1 and 2 are secured to all the side stakes along whichthe said members pass. These side stakes form the support of the woodenor metallic sides of the car, as the case may be. I prefer to place aside stake at each end of the body-bolster, as shown at 7 and 8, whileat the corners I may use a U- shaped member, as ap ears at 9.

At 10 are shown ying transoms, which may be of channel or othercross-section. They extend transversely from the sides of the car to thecenter sills 11 11, and they may either be flush with the top of thecenter sills to receive metallic floor plates or sheets, as illustratedin Fig. 3, or they may support stringers 12 12, as shown in Fig. 2, theupper sides of the said stringers being flush with the tops of thecenter sills to receive wooden floor-sheets 13 13, which may be spikedto the said stringers. The side and end walls of the car may also be ofwood secured by any suitable means to the side'stakes, or they may be ofmetal, as preferred. Wooden side walls are shown in Figs. 1 and 2 at 1414. If desired, end sills may be employed.

It will be seen that the structure herein described provides a car-sillwhich is in itself adequately suited to the purposes of such structuralelements of car construction. It will also be seen that in case ofaccident to the sill the parts thereof can be readily disassembled,straightened, and reassembled, or if a portion of the sill is brokenbeyond repair another part can easily be substituted or inserted in itsplace. i

This patent is intended to embrace only so much of the disclosure madeherein as is covered by the claims.

I claim as my invention 1. A side sill for railway-cars Whose centralportion is composed solely of an upper longitudinal compression-bar anda lower longitudinal sectional tension-bar in combination with sidestakes extending above said compression-barto which both of said barsare directly fastened, substantially as described.

2. In a car, a side sill extending beyond the body-bolsters, the saidsill comprising an angular compression member and a tension member madeup of three or more parts, butt-straps joining adjacent parts of thetension member, and vertical metallic side stakes or members uniting thesaid tension and compression members, substantially as described.

3. In a car, a side sill extending beyond the body-bolsters, the saidsill comprising an angular compression member and a tension member madeup of three or more parts, butt-straps joining adjacent parts of thetension member, and vertical metallic T-shaped side stakes or membersuniting the said tension and compression members, said T- shaped membersprojecting above the said compression member and Wooden or metallic carsides supported by the said stakes or T- shaped members, substantiallyas described.

4. In a car, a side sill extending beyond the body-bolsters, the saidsill comprising an angular compression member and a tension member madeup of three or more parts, buttstraps joining adjacent parts of the tension member, and vertical metallic T-shaped side stakes or membersuniting the said tension and compression members, all in combinationwith subsills extending to the ends of the car, substantially asdescribed.

5. In a car having Wooden sides, floors and ends, a side sill extendingbeyond the bodybolsters, the said sill comprising an angular compressionmember and a tension member made up of three or more parts, butt-strapsjoining adjacent parts of the tension member, and vertical metallicT-shaped side stakes or members uniting the said tension and compressionmembers, substantially as described.
